A sudden appearance of a growth resembling a polyp under the tongue?


I suddenly noticed a small growth under the tongue, specifically on the sublingual papilla.
It doesn't hurt, but I can feel my tongue touching it.
I just discovered it today.
Please have a look, thank you.

Sudden growths or changes in the oral cavity, such as the appearance of a small bump under the tongue (known as the sublingual area), can be concerning. It’s essential to understand that while many oral growths are benign, they can also indicate underlying conditions that may require medical attention.

The small growth you described could be a variety of things. Common possibilities include:
1. Mucocele: This is a fluid-filled cyst that can occur when a salivary gland duct is blocked or damaged. Mucoceles are typically painless and can appear as small, soft bumps. They often resolve on their own but may require surgical removal if they persist or cause discomfort.

2. Fibroma: This is a benign tumor made up of connective tissue. Fibromas can develop in the mouth due to irritation or trauma, such as biting the tongue or cheek. They are usually firm and painless.

3. Papilloma: These are benign growths caused by the human papillomavirus (HPV). They can appear as small, wart-like bumps and are generally harmless.

4. Lingual Thyroid: In some cases, a growth under the tongue could be a remnant of thyroid tissue that did not migrate to its normal position during development. This condition is rare but can occur.

5. Infection or Inflammatory Conditions: Sometimes, infections or inflammatory conditions can lead to swelling or growths in the mouth. Conditions like oral herpes or other viral infections can cause lesions or bumps.

6. Oral Cancer: While less common, any new growth in the mouth that persists for more than two weeks should be evaluated by a healthcare professional to rule out malignancy, especially if there are other concerning symptoms such as pain, difficulty swallowing, or changes in taste.

Given that you mentioned the growth is painless and you just discovered it, it is advisable to monitor it closely. If the bump changes in size, color, or if you begin to experience pain or other symptoms, you should seek medical advice promptly. A healthcare provider, such as a dentist or an oral surgeon, can perform a thorough examination and may recommend further diagnostic tests, such as a biopsy, if necessary.

In the meantime, maintaining good oral hygiene is crucial. Regular brushing and flossing can help prevent infections and other oral health issues. Avoiding irritants, such as tobacco and alcohol, can also be beneficial for your oral health.

In conclusion, while many oral growths are benign, it is essential to remain vigilant and consult a healthcare professional if you have any concerns. Early evaluation and diagnosis can lead to better outcomes and peace of mind. If you have any further questions or if the growth persists, do not hesitate to reach out to a healthcare provider for personalized advice and treatment options.
